IBM Sterling Ideas

Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

IBM is transforming its request for enhancement (RFE) process. The purpose of the transformation is to provide a more consistent experience for you to submit requests and to enable IBM product owners to respond to your requests more quickly. For more information click here.

Start by posting ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,
1. Post an idea
2. Upvote ideas that matter most to you
3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The offering manager team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notifications on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

B2Bi using Document Object Model (DOM) for XMLDsig requires a lot of RAM to handle payloads

Customer having a problem with XMLDsig where B2Bi is using Document Object Model DOM to handle XML payload by design. The issue is that it requires 2GB RAM to handle 130 MB payload. This is just for one file. The reason is that B2Bi processes in memory. Customer looking to consolidate all payment files from all corporate customers. The solution would not be feasible for the volume they want.

How will this idea be used?

We need to find a way for B2Bi to handle large amount of XMLDsig payloads without having to use RAM.

A 130MB of XML payload require app. 2GB of RAM to build and interact (sign the payload) with the DOM. From what we document, this seems to be a linear ration, so 2GB of XML payload would require app. 16GM of RAM alone – which is not really feasible when looking to consolidate all payment files from all corporate customers. The solution would not be feasible for the volume they want.
